Acute kidney injury (AKI) is an abrupt reduction in kidney function caused by
different pathological processes. It is associated with a significant morbidity
and mortality in the acute phase and an increased risk of developing End Stage
Renal Disease. Despite the progress in the management of the disease, mortality
rates in the last five decades remain unchanged at around 50%. Therefore there is
an urgent need to find new therapeutic strategies to treat AKI. Lysosomal
proteases, particularly Cathepsin D (CtsD), play multiple roles in apoptosis
however, their role in AKI is still unknown. Here we describe a novel role for
CtsD in AKI. CtsD expression was upregulated in damaged tubular cells in
nephrotoxic and ischemia reperfusion (IRI) induced AKI. CtsD inhibition using
Pepstatin A led to an improvement in kidney function, a reduction in apoptosis
and a decrease in tubular cell damage in kidneys with nephrotoxic or IRI induced
AKI. Pepstatin A treatment slowed interstitial fibrosis progression following IRI
induced AKI. Renal transplant biopsies with acute tubular necrosis demonstrated
high levels of CtsD in damaged tubular cells. These results support a role for
CtsD in apoptosis during AKI opening new avenues for the treatment of AKI by
targeting lysosomal proteases.
